Quick overview
There are four common solutions used in UK lofts: mineral wool (Rockwool), fibreglass, quilted/roll insulation and spray foam. Each has trade-offs for cost, performance and installation. Below we explain the pros, cons and the types we recommend for Barking & Dagenham houses.
Mineral wool (Rockwool)
What it is: Dense mineral fibres supplied as rolls or slabs and fitted between joists.
Why we recommend it: Excellent fire resistance, great acoustic properties and stable thermal performance. It's ideal for older terraced and semi-detached properties common in Barking.
Typical cost range: Mid-range; good long-term value.
Fibreglass
What it is: Glass-fibre batts or rolls laid on the loft floor.
Why homeowners choose it: Cheapest professional option, easy to install and good thermal performance when laid correctly — good for quick, budget-conscious upgrades.
Quilted / insulation rolls (yellow rolls)
What it is: Pre-formed rolls or quilted blankets laid between rafters or across the loft floor.
Why they’re common: Widely available, easy for professionals and sometimes DIY. They’re effective when installed without gaps and at the correct depth.
Spray foam
What it is: Liquid polyurethane sprayed into cavities where it cures into a sealed foam layer.
Pros: Top-tier R-value per mm and excellent air sealing — great for awkward lofts or when airtightness is needed.
Cons: Higher cost, requires specialist installers, and can complicate future loft alterations.
